| 摘 要： | 在20升热聚合反应釜中对中温煤沥青进行热聚合改质处理，研究了热解缩聚期间煤沥青软化点的变化规律，讨论了软化点在评价煤沥青聚合程度中的作用，并找出了热聚合改质过程中煤沥青软化点与结焦值和甲苯不溶物之间的关联性。 |
| 关 键 词： | 热聚合改质 煤沥青 聚合程度 |

| Abstract: | The regularity of softening point variation of coal tar pitch during the thermal polymerization modification has been investigated in a reaction still. The role of softening point in evaluating the polymerization degree of coal tar pitch has been discussed. The correlations between the softening point and the coking value and toluene insolubles have been found. |
| Keywords: | coal tar pitch thermal polymerization modification polymerization degree softening point |
